Uncompromised Innovation

When we gave our engineers free rein to create the best speaker they could, they came up with the revolutionary Concept Blade prototype - the world's first single apparent source loudspeaker. Its sonic capabilities were so impressive that we created an edition that serious audiophiles could actually own.
